Abstract
Official abstract text for this publication.
A power transmission device includes first and second rings arranged opposite each other, having a common rotation center axis, and rotatable relative to each other; a plurality of planetary balls having rotation center axes parallel to the rotation center axis, and radially arranged between the first and second rings and around the rotation center axis; a transmission control unit configured to change a rotation ratio between the first and second rings by changing the respective contact points of the first and second rings and each of the planetary balls through tilting motion of each of the planetary balls; and a rotation restricting unit disposed between the planetary balls adjacent to each other.
